When you hear “white tablecloth Italian joint,” a few things come to mind: stuffiness and formality or spaghetti in red sauce (“gravy” to many). But what if someone told you there’s a “white tablecloth Italian joint” in Philly that’s as swanky and chic as the food is carefully prepared, where you could take your corporation’s top brass or your hot date? It exists. It’s called Le Castagne. Italian for chestnut and aptly named for its spot on Chestnut Street, the food is spot-on, from burrata salad through the homemade pastas and dessert. Also open for lunch, Le Castagne is known to draw a discerning business lunch crowd. But one thing that sets this Northern Italian restaurant apart is its bar -- a gorgeous, floor-to-high-ceiling wood masterpiece that features a wine tap system and a rolling ladder. Whether you grab a drink before your meal, meet a few friends for happy hour or dine here and engage the bartender in some friendly banter, be sure to make a stop.
